Specification of Letters Patent.

Patented Feb. '13, 1912.

Application filed June 10, 1911. Serial No. 632,372.

To all whom 2'25 may concern:

Be it known that I, JOSEPH DVORAK, a subject of the Emperor ofAustria-Hungary, residing at Pittsburgh, in the county of Allegheny andState of Pennsylvania, have in vented certain new and usefulImprovements in Smoke-Separators, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to smoke separators designed for large and smallmanufacturing plants located in cities where smoke ordinances make itprohibitive for the free dis charge of smoke and gases from stacks andchimneys.

The primary object of my invention is to utilize water, air or steamunder pressure for condensing smoke and removing dust, ashes, dirt andunconsumed products of combustion from the smoke prior to its es cape,thereby preventing buildings and other property from being injured bydeposits of dust and other foreign matter.

Another object of this invention is to utilize a series of waterejectors for thoroughly saturating the smoke with water or steam,whereby the condensate will contain all the destructive properties ofsmoke emitted by a stack or chimney.

A further object of the invention is to provide an apparatus embodyingstructural elements that are compactly arranged, inexpensive to installand highly eflicient for the purposes for which they are intended.

With the above and other objects in view, the invention resides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed.

Reference will now be had to the drawings, wherein there are illustratedthe preferred embodiments of the invention, but it is to be understoodthat the structural elements' thereof are susceptible to such changes inthe size, shape and manner of assemblage as fall within the scope of theappended claims.

In the drawings :Figure 1 is a longitudinal sectional view of a smokeseparating apparatus especially designed for large manufacturing plants,Fig. 2 is a view of one end of one of the steam or air ejectors partlybroken away, Fig. 3 is a view of the opposite end of the ejector.

Like numerals of reference designate corresponding parts throughout theseveral views.

The reference numeral 1 denotes an elbow in communication with a stackorchimney, said elbow having the upper end thereof provided with aperipheral flange 2 and riveted or otherwise connected, as at 3 to theflange 2 is a peripheral flange 4, carried by the small end of ahorizontal frusto-conical shaped hood 5, the large end of said hoodhaving an exhaust pipe 6. This pipe has an opening 7 and incommunication with said opening is a drain pipe 8 having the upper endthereof flanged and secured to the pipe 6 by rivets 9 or other fasteningmeans.

10 denotes a water supply pipe extending through a nipple 11, carried bythe elbow 1, said water supply pipe extending longitudinally andcentrally of the hood 5. The pipe-10, adjacent to the nipplell, has anordinary type of gate or globe valve 12, whereby the supply of water tothe hood can be easily controlled. The portion of the pipe within thehood is eXteriorly screw threaded, as at 13 and arranged upon thethreaded end of said pipe is a blower or pump and a series of waterejectors, said ejectors being of different diameters and stepped intheir order, whereby the peripheral edges of said ejectors will be in aplane substantially parallel with the inner walls of the hood 5.

The blower or pump comprises a cupshaped casing 14 having the bottomthereof provided with an opening 15 and the walls of the opening arescrew threaded whereby the casing can be easily screwed upon the pipe10. The casing has an inlet nipple 16 adapted to be connected by a unionor other coupling 17 to a steam. or air supply pipe 18. This pipeextends through an opening 19 provided therefor in the hood 5, andadjacent to said hood the pipe has an ordinary type of globe valve 20.This valve is adapted to control the admission of steam or air to thecasing 14. Screwed upon the pipe 18 into the open end of the casing 14is a deflector head 21 adapted to engage the edges of the casing 14. Theperipheral edge of the deflector head 21 is provided with radiallydisposed grooves 20 adapted to disseminate steam or air ejected from thecasing 14.

The series of water ejectors consists of cup-shaped casings 23 havingthe bottoms thereof provided with openings 24 with the walls of saidopenings screw threaded, whereby the casings can be screwed upon thepipe 10. The pipe 10 has an opening 25 opening into each casing, wherebywater will be admitted to each casing. Secured upon the pipe 10 toengage the edges of the casings are deflector heads 26 similar to thehead 21, said heads having the peripheral edges thereof grooved, as at27 whereby the water admitted to the heads will be pro jected outwardlyfrom the casings in sheets toward the walls of the hood 5.

When the smoke from the elbow 1 enters the hood 5, it can expand withinthe hood, a draft being set up by the blower or pump that causes thesmoke to rapidly enter the hood 5. Then the smoke encounters the steamor air ejected by the peripheral edges of the steam ejectors, and thewater from the water ejectors, the smoke is driven toward the side wallsof the hood 5 and it is upon these walls that the condensate collectsand gradually travels toward the opening 7 into the drain pipe 8. Thecondensate, produced by the smoke commingling with the steam and water,contains all the dust, ashes, carbon'products, soot, unconsumed productsof combustion and foreign matter originally held in suspense by thesmoke, consequently only steam will escape from the exhaust pipe 6.

The advantage of the stepped arrangement of the steam and water ejectorsis that the smoke is carried toward the walls of the hood 5 and thesewalls collect the condensate, it being practically impossible for thesmoke to escape through the hood 5, without encountering the radiatingsheets of steam and water from the ejectors.

In the preferred form of construction, the

condensate drains toward the exhaust of the stack or chimney.

The apparatus is constructed of light and durable metal. and it will ofcourse be understood that it is applicable to locomotives and varioustypes of power producers.

hat I claim is 1. A smoke separator comprising a frustoconical hood, anelbow for connecting the contracted end of the hood to a stack, a liquidsupply pipe extending longitudinally with respect to said hood andprovided with spaced openings constituting outlets, a se ries of spacedliquid ejectors mounted upon said pipe and each surrounding an outlet,the diameters of the respective ejectors increasing to provide a seriesof ejectors having the peripheral edges parallel with the inner face ofthe hood, and a blower mounted upon said pipe ahead of the ejectors inthe direction of flow of the gases.

2. A smoke separator comprising a frustoconical hood, an elbow forconnecting the contracted end of the hood to a stack, a liquid supplypipe extending longitudinally with respect to said hood and providedwith spaced openings constituting outlets, and a series of spaced liquidejectors mounted upon said pipe and each surrounding an outlet, thediameters of the respective ejectors increasing to provide a series ofejectors hav ing the peripheral edges in a plane parallel with the innerface of the hood.

In testimony whereof I affix my signature in the presence of twowitnesses.
